Stocks across most Arab markets advanced on Sunday as the risk of a military showdown between the U.S. and Russia in Syria that would roil the region faded.

Saudi Arabia’s Tadawul index led the advance as all but one stock rose, and Dubai’s main equity gauge climbed the most since June. Shares in Abu Dhabi gained as much as 1.3 percent, sending the benchmark index to the highest level on a closing basis since August 2015.

The U.S., U.K. and France attacked targeting military positions and research facilities linked to chemical weapons in Syria over the weekend. While Russia, Iran and Lebanon’s Hezbollah group rallied around Syrian President Bashar Al-Assad’s regime, they didn’t threaten any retaliation. Saudi Arabia said it would take part in the U.S. coalition if asked.

Investors have had two days to reflect on the strike, so the operation isn’t a factor that would prompt traders to sell anymore, said Mohammed Ali Yasin, the chief executive officer of FAB Securities in Abu Dhabi. What they’re focused on is company results, he said.

Saudi Arabia’s stocks on Wednesday fell the most since October after U.S. President Donald Trump’s comments on Twitter suggested that strikes against Syria were imminent. On Sunday, the Tadawul All Share Index climbed 1.9 percent, the most since June.
